Frequently Asked Questions
How many pins does the TFM-139-22-SM-D-A-P-TR have and what is its board stacking height?
The TFM-139-22-SM-D-A-P-TR features 78 pins arranged in a dual row of 39 pins per row on a 1.27 mm (0.050-inch) pitch. The 2.20 mm stacking height makes this Tiger Eye SMT terminal strip ideal for thin board-to-board stacking assemblies in space-constrained embedded and aerospace designs.
What operating temperature range does the TFM-139-22-SM-D-A-P-TR support for harsh environments?
SAMTEC Tiger Eye terminal strips operate from -55°C to +125°C, meeting aerospace and industrial reliability requirements. The 78-pin dual-row SMT design withstands automated reflow soldering and repeated thermal cycling, maintaining consistent contact resistance and mating force throughout the full rated operating temperature range.
For a 78-pin bus interface design, when would TFM-139-22-SM-D-A-P-TR outperform a 2.54 mm pitch connector?
When routing 78 pins at 1.27 mm pitch, the TFM-139-22-SM-D-A-P-TR consumes roughly half the board length of an equivalent 2.54 mm pitch connector, freeing critical PCB real estate in FPGA carrier boards, defense modules, and high-speed data acquisition systems requiring signal bandwidths above 500 MHz.
